ATTORNEY FIGS.

Patented Dec. 23, 1947 UNITED STATES "PATENT OFFICE CULTIvA'roR SHIELDFrank F. Carter, Merkel, Tex. Application August 4, 1945, serial No.ossos My invention relates to improvements in cultivator shields.

The primary object of the invention is to provide cultivator shields ofrotary disk type which are readily adjustable while the cultivator is inmotion from a tractor seat.

Another object of this invention is to provide cultivators with shieldsthat can successfully be used in the cultivation of terraces.

Another object of this invention is to provide cultivator shields thatwill not hold weeds, trash or other obstacles which prevent theirfunctioning.V

Another object of this invention is to provide cultivators with shieldshaving a rolling motion instead of the usual sliding motion, thuspermitting greater maneuverability of the cultivator.

Other objects and advantages of this invention become more apparent fromthe following description and reference to thev accompanying drawings inWhich- Figure 1 is a side view of cultivator shields attached to acultivator, which is on a tractor ready for use.

Figure 2 is a partial top View of Figure 1, showing the shields attachedto one side of the cultivator,

Figure 3 is a side view of the shields showing their raised position indash lines.

Figure 4 is a front view of the shields, parts being shown in section online 4-4 of Figure 3.

Figure 5 is a sectional View on line 5-5 of Figure 3.

Figure 6 is an isometric perspective View of the vertical adjustmentnut.

Figure '7 is a front end elevational view of the frame supporting clamp.

Referring to the drawings, and more particularly to Figures l and 3, itwill be seen that reference numeral IU indicates rotatable disk-likeshields that are supportedl by axle II on a V- shaped angular frame I2by means of bearings I3. Shields I0 are adjustable laterally along axleII by set screw I4 on the shield hubs I5 (Figure 4). Axle II is kept inplace by collars IB, as also shown in Figure 4.

One arm of the V-shaped frame I2 is supported at the front by a clamp I1that in turn is attached to clamp I8 carried by the cultivator frame bymeans of pivot bolt I9 (Figures 3 and '7), or other suitable means. Theother arm of the V-shaped frame I2 is suspended from rod 20 passingthrough a lug 2I carried by the frame. Adjacent one end of rod 20 isadjustably secured a collar 22 whose use will be fully describedhereinafter.

4 Claims. (Cl. 97-188) Passing through the front end of rod 20 is a pin23 which thus attaches the said rod to the lower end of supporting lever24 rotatably mounted on the frame of the cultivator. The

` upper end of lever 24 supports a vertical adjustment nut 25 throughwhich passes the threaded end of an adjusting rod 26. The rear end ofadjusting rod 26 is supported by a bearing carried by a clamping rod 21that is attached to the outside lift pipe C1 of the cultivator C. Therearmost end of rod 2B is formed into or attached to hand crank 28 bywhich means the cultivator shields are adapted to be vertically adjustedfrom the seat of tractor T while the said tractor is in motion.

The cultivator shields I0 are attached to the cultivator C by means ofclamps I8 and a rotatable support 29 carried by the cultivator frame.Rotatable support 29 supports and is part of lever 24 as is clearlyshown in Figures 3 and 4. Indirectly the cultivator shields are alsosupported by the bearing 21.

It is understood, of course, that a cultivator is made into twosections, right and left hand. Only the right hand section and thecultivator shields for the right hand section are shown in thesedrawings.

To operate these shields when the cultivator is in motion it is onlynecessary to turn the crank 28 which raises or lowers the frame I2 andsaid shields I 0 as shown in dash lines on Figure 3; (dash lines showupward position of shields). To a certain extent the shields will alsobe raised or lowered whenever the cultivator outside pipe lever C2 ismoved. This can be readily understood on examination of Figure 1, sincethe bearing 21 is attached to outside lift pipe C1 which is movable byoutside lift pipe lever C2; and any movement of this said lever will inturn transmit vertical motion to cultivator shields I0 by means of theadjusting rod 26, adjustment nut 25, supporting lever 24, pin 23, rod20, frame support lug 2I, frame I2, bearings I3, axle II to circularshields II).

The extent of vertical adjustment of shields I0 and frame I2 may beregulated by the position of collar 22 along rod 20, which collarnormally abuts against the lug 2|, whereby through forward movement ofrod 20 lifting motion may be transmitted to frame I2.

Horizontal adjustment of the frame I2 and of disks I0 is obtained bysliding the lower front ends of frame I2 forward or backward throughadjusting clamps I1 and tightening adjustingl screws I 11.
